This invention relates to a window, and more particularly to a manually-operable mechanism for operating a window. i

The object of the invention is to provide a mechanism which is adapted to be manually operated in order to open and close a window.

Another object of the invention is to provide a window-operating mechanism which includes an actuating handle that can be pivoted or moved to back out of the way when not in use, the parts of the mechanism being interchangeable so that the mechanism can be used for windows which open from either the left or right side.

Another object f the invention is to provide a window-operating mechanism which is extremely simple and inexpensive to manufacture.

Other objects and advantages will be apparent during the course of the following description.

Referring in detail to the drawings, the numeral designates a portion of a window frame which is provided with a slot or opening 2| therein, Figure 1. A window 22 is hingedly connected to the frame 20, the window 22 being mounted for opening and closing movement with respect to the window frame 20. The window 22 includes a glass pane 23, there being a groove or channel 24 arranged in the bottom of the window 22 for a purpose `to be later described. The window 22 is hingedly connected to the frame 29 by means of hinge parts 26 which are pivotally connected to corresponding hinge parts 25 by a pin 2l. The hinge parts 25 are secured to the frame 26, while the hingle parts 26 are secured to the window 22.

The present invention is directed to a manually-operable mechanism for opening and closing the window 22, and the mechanism includes a hollow housing 28 which is provided with a transverse flange 29, and a plurality of securing elements, such as rivets 39, project through the flange 29 and into the frame 29 for connecting the housing to the frame. Y

The housing 28 may be fabricated of any suitable material, and the housing 28 includes a top wall 3|, Figure 8, and a bottom wall 32, there being an end Wall 33 arranged between the top and bottom walls. The end wall 33 is provided with an elongated slot 34, Figure '1. Rotatably supported in the housing 28 and extending between the top and bottom walls thereof is a hollow, cylindrical spindle 35. An actuating arm 36 iS keyed, as at 31, Figure '7, to the spindle 35, so that as the spindle 35 rotates, the actuating arm 36 rotates therewith. The other end of the arm 36 is provided with a bushing 38 which slidably projects in the groove 2li in the bottom of the window 22, so that this movement of the actuating arm 36 causes opening and closing movements of the Window 22. The inner end of the arm 39 is provided with an enlarged body portion 39, there being a central opening il!) arranged in the body portion 39, Figure 6, and the opening 40 snugly receives therein the spindle 35. Arranged along one side of the body portion 39 is a plurality of spaced teeth or serrations 5i, while arranged along the opposite side of the body portion 39 is a similar plurality of teeth i2 for a purpose to be later described.

Slidably projecting through the slot 34 in the housing 28 is a hollow casing iE-3, Figure 10. The casing t3 is provided with a channel 44, there being an opening 45 arranged in the inner end of the casing 43 for rotatably receiving therein the spindle 35. An actuating handle 45 is reciprocably or slidably mounted in the channel M of the casing 43, and the inner end of the handle 46 is shaped to define a nger or lug 4l, the nger 41 being mounted for movement into and out of registry or engagement with an opening 48 that is arranged Vin the spindle 35. Thus, when the iinger 41 is projecting through the opening 48, rotation of the handle 46 will cause rotation of the spindle 35, but when the nger 41 is retracted from the opening 48, the handle 46 and casing 43 can freely rotate about the spindle 35. By means of this construction, the handle 46 and casing 43 can be swung or moved to an out-ofthe-way position when notl being used.

Arranged in the housing 28 is a washer 49, Figure 2, and the washer 49 is provided with a large opening 50 for loosely receiving therein the spindle 35. The washer 49 is interposed between the casing 43 and the arm 36, Figures 7 and 9.

A pin l pivotally connects one end of the arm 36 to the washer 49, there being a cutoutl or split 52 arranged in the washer 49. Carried by the inner end of the handle 46 is a pin 53 which is mounted for movement into and out of engagement with the cutout 52 in the washer 49. The pin 53 slidably projects through a slotl 54 in the upper surface of the casing 43. Thus, as the handle is reciprocated back and forth in the casing 43 by means of the knob 55, the pin 53 can be moved into and out of engagement with the cutout 52. 'I'he handle 46 is provided with a cutaway portion or recess 56, Figure 10, and a lug 51 projects upwardly from the bottom of the casing 43 and into the recess 56. A coil spring 51' is interposed between the lug 51 and the handle 46, and the coil spring 51 serves to normally urge the finger 41 into the opening 48 and the pin 53 into the cutout 52.

A dog 58 has one end pivotally connected to the top wall 3l of the housing 28 by a pin 66, Figure 2, and the dog 58 includes a pointed end 59 that is mounted for movement into and out of engagement with the teeth 4I of the body portion 39. A spring member 6I normally urges the pointed end 59 of the dog 58 into engagement with the teeth 4 I. Carried by the dog 58 is a pin 62, and the pin 62 is adapted to be engaged. by the washer 49, whereby the pointed end 59 can be moved out of engagement with the teeth 4l. Arranged on the opposite side of the housing 28 is a similar dog 63 which includes a pointed end 64 that is mounted for movement into and out of engagement with the teeth 42. The dog 63 is normally urged into engagement with the teeth 42 by a spring member 66, the dog 63 being pivotally connected to the top wall 3l of the housing by a pin 65. Carried by the dog 63 is a pin 61 which is adapted to be engaged by the washer 49', whereby the dog 63 can be moved out of engagement with the teeth 42 so as to permit turning movement of the arm 36.

The pointed ends of the dogs 58 and 63 are normally urged into engagement with the teeth 4| and 42 of the arm 36 by means of the spring members 6l and 66. Thus, it is impossible to turn the arm 36 and the window 22 unlessv the dogs 58 and 63 have been urged out of the respective teeth on the arm 36.

To open or close the window, the user merely swings the manual handle 46 from its dormant position, as indicated by the dotted lines in Figure l, away from the frame 26 until the nger 41 enters the hole 48 in the spindle 35. At the same time, the pin 53 is engaged in the cutout or notch 52 provided for it in the washer 49. The ringer 41 is made so that it is a loose t in the hole 48, whereby the arm 46 can be moved slightly before the spindle 35 moves. When the window is being closed, the handle 46 is moved to the right. At the same time, the washer 49., which is pivoted on the pin 5I and which. has

(Sii

its edges in contact with the studs or pins 62 and 61 of the dogs 58 and 63, moves to the left, forcing the dog 58 out of the teeth 4| on the arm 36 and thus permitting the arm 36 to be moved to the left. As soon as the pressure is taken from the arm 36, both dogs 58 and 63 will again engage the teeth on the arm 36 whereby accidental rotation of the arm will be prevented. When the window is being opened, the handle 46 is moved to the left, whereby the dog 63 will be moved out of the teeth 42 so that the arm 36 can be moved to the right.

When the window has been set at a desired position, the handle 46 is pulled outward, disengaging the pin 41 from the hole 48 in the spindle 35. This permits the handle 46 to be swung over against the window frame out of the way.

From the foregoing it is apparent that a window-operating mechanism has been provided wherein the handle can be shoved back against the Window frame when not in use. Also, the locking dogs are automatically released when the window is being opened or closed. Also, the cost of manufacturing the window-operating mechanism is extremely small.
